Keys to interpretation

What structure is being imaged?

Where is the cursor?

Size

Septum in HOCM

Timing

Tamponade - diastolic collapse

Density

Myxomatous leaflets, masses

Technology

A single crystal rapidly alternates between transmission and receiver modes with rapid updating result, rapidly moving structures (eg, valve leaflets) can be monitored for their characteristic motion very high temporal resolution
